STM32H743 Nucleo board

I once called this the "Horse Pill" because it is so big. It is big both in capability (480 Mhz, 2M flash, 1M ram) and in physical size (nearly 3x5 inches). For comparison, the "blue pill" is pretty much 1x2 inches.

I bought my STM32H743 Nucleo-144 from Digikey in December of 2020 for $30 and of course got it in short order via the US mail.

Here is a link to my Github repository with my H743 experiments:

• Overview
• Manuals
• First power up.
